https://devzone.nordicsemi.com/f/nordic-q-a/65720/how-to-use-j-link-rtt-viewer-instead-of-rtt-on-embedded-studioHi. I&#39;m using ES. RTT(Debug Terminal) on ES works fine. But sometimes I want to use J-link RTT viewer. How can I turn off RTT on ES and then use J-link RTT viewer? I hope you reply.en-USTelligent Community 13Wed, 09 Sep 2020 06:44:13 GMThttps://devzone.nordicsemi.com/thread/268634?ContentTypeID=1Wed, 09 Sep 2020 06:44:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e8f5b8e-1f6f-4604-b2a2-2b505767fec8Roger01<p>Thank you very much</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/268633?ContentTypeID=1Wed, 09 Sep 2020 06:41:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:13484660-494a-4a33-8621-08b4bd446fa6Martin Lesund<p>Hi Roger,<br />You should be able to turn this OFF in settings:<br /><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-234667a420104d0dba766d111c11fc2e/pastedimage1599633692752v1.png" alt=" " /></p><div style="clear:both;"></div>
